My thoughts on the engine (S54B32) We're mixed at first, I was just getting into cars back then, im only 20 now I thought that the engine was terrible because it was only a 12HP more than the S52B32) And yet the e46 weighed 240 pounds more. Then as I started getting more and more into cars and I saw how different the two were, from a technological/dynamic standpoint and was like "Oooooohhhhh, I get it now"
